These are constants defined in <AudioUnit/AudioUnitProperties.h> on
Mac OS X.
Since we don't have these headers on Windows, you can just define
them yourself somewhere:
enum {
kRenderQuality_Max = 0x7F,
kRenderQuality_High = 0x60,
kRenderQuality_Medium = 0x40,
kRenderQuality_Low = 0x20,
kRenderQuality_Min = 0
};
Feel free to file a bug so that we put these in one of the QT headers
in a future release of the sdk.

Hello,
looking in QuickTimeComponents.h for
kQTSCAudioPropertyID_RenderQuality one can find mention of the
following constants:
kRenderQuality_Max, kRenderQuality_High, kRenderQuality_Medium,
kRenderQuality_Low, kRenderQuality_Min
which (allegedly) are defined in AudioUnitProperties.h but
unfortunately there is no such include file for the Windows QT SDK
version 7.1
an indication of what such constant values might be is provided in
Movies.h for the property:
kQTAudioPropertyID_RenderQuality
0x00 (kRenderQuality_Min) to 0x7F (kRenderQuality_Max)
does annyone know the values for all the render quality constants?
best regards,
andrea
